The accepted scientific name for Ashe juniper is Juniperus ashei
Buchholz. Ashe juniper is thought to hybridize with redberry juniper
(J. pinchotii) . Adams and Kistler summarized a number of
studies that investigated the report that Ashe juniper hybridizes with
eastern redcedar (J. virginiana) . They concluded that there was
no evidence of gene flow between the two species, even though their
ranges overlap, and morphological intermediates exist. There are no
recognized subspecies, forms, or varieties of Ashe juniper.

Ashe juniper has a limited range in southwestern North America. It
occurs in disjunct populations in southwestern Missouri and Arkansas, in
the Arbuckle Mountains of southern Oklahoma, and in Coahuila, Mexico.
The main population occurs in west-central Texas, largely on the Edwards
Plateau .

Ashe juniper forms dense to open communities with oaks (Quercus spp.),
including live oak (Q. virginiana) and Mohr oak (Q. mohriana), Texas
persimmon (Diospyros texana), and mesquite (Prosopis spp.). These
communities have invaded many acres of adjacent little bluestem
(Schizachyrium scoparium) grasslands as a result of overgrazing and fire
suppression .
